(Get the code!)
I mentioned in a previous entry (#43), my HP desktop needed a check-up by my "hardware consultant" due to the many hard resets.
Currently, the machine runs on its original OS Windows Vista without any problem and without any replacements needed. Discussing the issue with this consultant and others, we noticed that "a problem with the heat control could explain" the behaviour observed". (so ACPI). Running the program SpeedFan on Vista did not show a problem, however. So Vista is better than Linux for my HP (oops, never thought I would be able to write that down)
It could be a wild speculation, but I am suspicious about the transition from kernel 2.6.31 and 2,6.32 regarding the ACPI code of the kernel. I have the following arguments:
a) booting with acpi=off helps as mentioned a.o. by databubble (see item #39)
b) There is a variety of failures mentioned by different people, (with or without mouse, keyboard, wireless , heavy graphics load, etc etc). The different computers, different hardware configurations could explain why this variety is occurring, but heat problems may explain the failures of peripherals and kernel.
c) Still looking into the changes made, but apparently a lot has been changed with the introduction of 2.6.32 regarding power control and speedup during booting. Regression testing not rigorously enough for all hardware?
For the record my computer is a HP m8000, without ability to control the ACPI on the bios (setting S1 or S3 for instance).
I cannot afford to install Ubuntu Lucid with 2.6.32 at this moment, I will install a Linux (OpenSuse, Mandriva, Ubuntu 9.10) with 2.6.31 or even older kernel.
